SEEDING-MACH'INE.

SPECIFICATION forming part of Letters Patent No. 240,553, dated April 26, 1881.

Applicatihn filed September 27,1880. (Model.)

. State of Ohio, have invented certain new and .its bottom slanting from front to rear.

useful Improvements in Seeding Machines; and I do hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to an improvement in the feed mechanism of. seedingmachinesof that class which employ stationary feed-wheel compartments or cases and sliding feed-wheel shafts, to which thefeed-wheels are secured, and by shifting which shaft the feed is regulated.

The novelty of my invention consists in the construction and combination of the parts forming my device, as will be herewith set forth and specifically claimed. In the accompanying drawings, Figurel is a rear elevation of my improvedfeed mechanism asapplied to the seed box or hopper. Fig. 2 is a plan view of the same. Fig. 3is an end elevation through the line war of Fig. 1. Fig. 4 is an end elevation through the line y y of Fig. 1. Fig. 5 is a bottom-plan view. Fig.6is a rear elevation of a modification of my invention. Fig. 7 is asectional plan view through the line 1 l of Fig. 6. y I y The, same letters of reference indicate like parts in all the figures.

A represents the seed box or hopper, of the usual or any suitable construction, but gith his bottom B does not join the-rear side of the hopper, .butterminatesat a, as seen in Fig.3, leaving an. opening the entire lengthof the.

hopper, which openingis closed by metal plates, forming part of the wheel-casings, as explained farther on. Each wheel-casing consists of the cast-metal cups 0, twice the length of the contained feed-wheels, with rounded bottoms b, attaching-earsc, by which it is fastened to the hopper, a vertical rear side, d, containing. the discharge-outlet, and ribs or webs e on each side of this outlet. I I

I The construction and location of the parts will be readily understood by reference to the drawings.

The "right-hand end of the casing from the rear has a circular aperture, in which is fitted, by means of the overlapping detent f and hottom plate, D, with retaining-flanges g, Fig. '1, an annular fluted ring or washer, E, held from displacement, but free to revolve- The end of the plate D and this washer, which is of greater diameter than the feed-wheel, forms the end wall of the casing at this side. The opposite end of the casing is open to receive the sliding follower F, which is a piece of metal of the shape indicated, and either hollow or solid, as desired. The feed shaft Gpasses concentrically through the washer and through an aperture in the follower F. t The feed-wheel H, which is an ordinary fluted wheel as used in this class of machines, en.-

compasses the feed-shaft and fits through the scallops of the washer. It is held at a distance about equal to its own length from the end of the follower by a non-rotating sleeve, I, which encompasses the shaft and has its end enter ing the end of the follower. Pins hand 't", passed through the feed-shaft next to the outer ends of the follower and feed-wheel, serve to connect the follower, the sleeve I, and the feed-wheel to the shaft and-to each other, so that their relative positions are always maintained though the e by sliding the shaft.

To secure the rotation of the feed-wheel with I the shaft G, I employ a collar'or sleeve, J,

ntire set may be shifted which encompasses the shaft at the outer end of the feed-wheel, and has teats j, which enter corresponding aperturesin the end of thefeedwheel. A spiral spring, K, within this sleeve,

. 5 and secured at one end to the shaft and at the other. to the sleeve, serves to keep the'teatsini engagement with the wheel.

The pin ihefore mentioned fits into slots cut in the abutting.

end of the sleeve, and serves as a lock to con- .nect the sleeve" to the shaft and the-feed,

wheel to the sleeve, so that the rotation of the} shaft is imparted through the sleeve to the-"I;-

feed-wheel.

Now, whenever it is desired to "i stop the rotation of one or more of the. feed- 5.

wheels for any purpose, it. is only necessary to I draw back the sleeve J, by which the teats are withdrawn, and by then partially turning the sleeve the teats can be made to bear against the pin i, notches being made inthe teats for this purpose, as seen in Fig. 6.

L, Fig. 1, is the cut-off plate, which is made ICO detachable, for the purpose of enabling the cups to be cleaned out from the inside or outside, as desired, in changing the grain, as from wheat to oats or rye, or vice versa. This cutoff is aflat plate with a vertical slot, 1, at its inner end, and a groove or gutter, m, at its bottom edge, as seen in Fig. 2.

Upon the sleeve- I, next to the feed-wheel, is a rib or extension, a, which projects flush with the mouth of the discharge-aperture, and through the web 6 is a vertical slot, 0, to permit the passage of the cut-off through it, and acting as a guide for the same. By slipping theend of the cut-off through this slotin the web it may be attached to the extension n by slipping the slot 1 over the same and pressing the cut-off down until its gutter rests upon the bottom edge of the discharge-orifice. The upper. edge of the cut-off is thus brought in line with a horizontal slot or way, 19, formed in the casin g at the upper side of the discharge-opening. This construction attaches the cut-off to the sleeve I, so that upon sliding the shaft the cut-off gradually closes the discharge-aperture and regulates the amount of grain discharged. At the same time the feed-wheel is projected more or less through the washer upon the outer side of the casing. Upon the cut-off is marked ascale,r, which, in connection with a pointer, 8, upon the casing, enables the machine to be set to sow any amount of grain desired to the acre. These scales may be upon each cut-off of the series, and one may be constructed for oats, another for wheat, and so on.

Attached to the casingin any suitable manner is a saddle, P, which partly covers the wheel, as represented.

An essential feature of my invention consists in elongating the cup and interposing the preferabl y non-rotating sleeve I between the feedwheel and follower, for by this arrangement all liability of crushing the grain isprevented and the adjustment of the feed can be effected while the machine is in operation. It also enables me to clean the-cups thoroughly by first removing the cut-ofi' and then shifting the feedwheels. so that they project entirely upon the outside of the casin g.

" Insteadof the above construction, the modification shown in Figs. 6 and 7 may be employed, In the modification an ordinary cup, C,--1 nay be" employed, having the scalloped washer-in one end for the wheel to slide through, and having cast upon the opposite end a cylinder, A to form the extension of the cup. This cylinder opens into the cup and has its rear side cut away upon the lines a b. The follower, in this instance, may be simply a plate or disk, fitting into the cylinder and separated from the wheel, as in the former instance, and the cut-off slide L may be' attached to or formed integral. with the follower, as shown.

In some cases the non-rotatin g sleeve I may be dispensed with, and the feed-wheel and follower may be adjusted at their proper distances from each other upon the shaft by pins or any suitable means.

Another feature of my invention consists in a novel spout-hanger, which consists of two studs or pins, 25, Fig. 5, with swells u, and held projected through orifices in the bottom flanges or ears of the casing by a spiral spring, o. By pressing upon the pins they will be forced back through their orifices and permit the spout, (not here shown, but of the ordinary construction) to he slipped over them until the holes in the spout are in line with the pins, when the spring will project them and'effect a look, as

will be readily understood.

Having thus fully described my invention, I claim- 1. In the force-feed mechanism of seedingmachines of that class in which the feed-wheels are secured upon a sliding shaft, the combination, With the cup or wheel-casing, of the feedwheel revolving and sliding therein and of a length equal to about one-half of the casing, as and for the purpose specified.

2. In the feed mechanism of seeding-machines, the combination, with the elongated cup or Wheel-casing, of the feed-wheel revolving and sliding therein, and a follower adapted to fit into and form a sliding end wall of the cup, and separated from the wheel by a sleeve embracing the feed-shaft, substantially as described.

3. In the feed mechanism of. seeding-machines, the combination, with the cup or casin g, of a cutoff slide detachably connected to a sleeve interposed between the feed-wheel and a sliding follower, and adapted to open or close the discharge-orifice, substantially as described.

4. The com bination,with each feed-wheel and 5. The combination, with the feed-cup, of;

spring spout-hangers, consisting, of recessed ICC pins connected by a spiral spring,,substan tially as specified.

In testimony whereof I have hereunto set-- my hand.
